Granted: 1995-11-13
Abstract: A signal routing system for use in cellular RF communications systems wherein a signal can be routed to different antennas, effectively switching transmitters between antennas. The switching is accomplished by placing a frequency responsive device (7) between a transmitter and each antenna. The transmitter is then coupled to an antenna through the frequency responsive device (7) that has a resonant frequency equal to the transmitter's frequency. If the transmitter changes frequency, it will be switched to the appropriate antenna through the corresponding frequency responsive device (7). This system permits a sector of a cell to increase the number of frequencies in that sector to handle increased mobile traffic loads.

The device includes a tapered hole(22) for adjusting the specimen(33) position to keep normal to the ion gun, a rotary disk(23) of a doughnut shape having a rectangular protrusion(23a), a specimen position adjuster(20) having the protrusion(21) of a hemispheric shape, a shaft(31) inserted into the hole(22), ane under plate(32) having the groove(32a) receiving the rectangular protrusion(23a) to be flush with the upper plate(23) when the protrusion(21) and the concave surface(32b) are fitted to each other, and the upper plate(23).

Title: Method of artificial stone
Inventor: PARK NO-CHOL
IPC: C04B35/16
Filed: 1992-07-09
Granted: 1994-06-20
Abstract: The manufacturing method of an artificial stone comprises (a) mixing 100% silica sand, 70% feldspar powder, 6% stone powder, and an inorganic pigment, flux, sodium silicate, (b) homogeneously coating the surfaces of silica sand particles with this mixture by hot drying at 100-200 deg.C for 10-20 min., (c) press-molding the coated mixture to which sodium silicate is added according to quality and color, (d) hot-drying the molded body at 100-150 deg.C, heating it at 750-850 deg.C for 30-60 min., and annealing, (e) impregnating synthetic resin solution to the dried body, and polymerizing, curing the infiltrated resin in an artificial stone to seal voids and pores by heating at 150-200 deg.C.
